BINDER.

Specification of Letters Patent.

Patented Feb. 13, 1906.

Application filed December 31, 1904. Serial No. 239,123.

To all whom it may concern:

Be it known that 1, CHARLES LANDON DON- OHOE, a citizen of the United States, and a resident of Santa Barbara, in the county of Santa Barbara and State of California, have invented a new and Improved Binder, of which the following is a full, clear, and exact description.

The invention relates to a binder for leaves or papers of various sorts, but is especially adapted for use in what is known as the perpetual ledger system of bookkeeping.

The object of the invention is primarily to produce an eflicient, easily-operated, and practically-indestructible or all-metal binder. I attain this end by means of certain novel features of construction and arrangement of parts, which will be fully set forth hereinafter and pointed out in the claims. 1

Reference is had to the accompanying drawings, illustrating as an example the preferred embodiment of my invention, in which drawings like characters of reference indicate like parts in the several views, and in which Figure 1 is a longitudinal section taken through the back of the binder on essentially the line 1 1 of Fig. 2. Fig. 2 is a cross-section on the line 2 2 of Fig. 1, showing the binder locked. Fig. 3 is a sectional elevation on the line 3 3 of Fig. 1, also showing the binder locked, but showing one of the covers in open position. Fig. 4 is an inner plan view looking toward the back of the binder and showing the filing-pins and parts of the covers. Fig. 5 is a view essentially the same as Fig. 3, except that the binder is in open position. Fig. 6 is a detail section on the line 6 6 of Fig. 5, and Fig. 7 is a detail view of the cam for operating the dog.

The'back of the binder is made up of a main part 10 and an inner frame-plate 11, these parts being fastened together by screws 12 and being formed, preferably, of a suitable metal. At each end of the back is secured a housing 14, and at one side of the plate 11 is securely fastened a clamping strip or section 15. This clamping strip or section 15 is movable with respect to the back of the binder and is secured firmly to the adjacent edge of the plate 11 and to the housing 14. At the opposite edge of the plate 11 a movable clamping strip or section 16is arranged. This is provided with lugs, which are hinged on a pin 17 arranged at said edge of the plate 11. The movable clamping-strip 16 carries, referably, four arc-shaped filing-pins 18, w 'ch when in active position extend over into openings 15 in the clamping-strip 15. At the side of the binder on which the clampingstrip 15 is located a cover 19 is connected to a hinge-pintle 20, secured to the adjacent edge of the plate 11. At the other side a cover 21 is provided with a hinged plate 22, joined to the aforesaid pin 17, the hinged parts of the cover 21 and clamping-strip 16 lying alternately on the pintle 17 as indicated in Fig. 4.

The housings 14, the clamping-strips 15 and 16, the covers 19 and 21, and all of the other parts of the binder are preferably constructed of a suitable metal. This makes an extremely strong construction and at the same time one which is durable to the extent of being practically indestructible.

It will be observed that the cover 19 may be swung freely to open or closed position irrespective of the clamping-strip 15 and that these same operations may be performed by the cover 21. The clamping-strip 16, however, is free to swing (subject to the action of certain locking devices to be hereinafter explained) from the closed position shown in Fig. 2 to the open position shown in Fig. 5. In this open position the pins 18 are disengaged from the clamping-strip 15 and moved considerably away from the same, so as to allow all of the leaves or sheets in the binder to be removed, if desired, as a unit or to permit them to be removed separately, as conditions may require.

Located in each housing 14 is a rocker 23, pivoted on a pin 24 and having a notch 25 in its periphery with which coacts a stop-pin 26, limiting the movement of the rocker. Each rocker 23 is connected by a link 27 with the swinging clamping-strip 16, so that when the rockers are in the positionshown in Fig. 3 they hold the said clamping-strip firmly in locked position and When in the position shown in Fig. 5 they throw the clampingstrip to open or inactive position. Each rocker is provided with an opening 28, and with these openings coact dogs 29, the dogs engaging in the openin s to hold the rockers in locked position. Said dogs are carried by forked springs 30, the arms of which are fastened within the housings and the free parts of which coact with cams 31, also located within the housings. These cams are fastened to a shaft 32, which extends longitudinally of the back through an opening 33 in the body 10 thereof. The shaft is arranged to turn in slotted lugs 34, projecting from the housings, and it is held from displacement by means of interengaging staples or pins 35, secured to the back and to the shaft. One of the housings is formed with an opening 36 therein, at which the square end of the shaft 32 is exposed to permit the application of a key to said shaft.

By turning the shaft so that the cams 31 engage the free parts of the springs 30 the dogs 29 may be disengaged from the openings 28, and the rockers 23 will be free to turn, so as to permit opening the binder. When it is desired to close the binder, the shaft 32 should be turned to disengage the cams 31 from the springs 30, and then upon closing the clamping-section 16 the rockers 23 return and the pins 29 spring back into the openings 28, thus securely locking the parts together.

Various changes in the form, proportions, and minor details of my invention may be re sorted to at will without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as may lie within the intent of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A binder comprising a back, a housing at one end thereof, a stationary clampingsection secured to one edge of the back and to said housing, a second clampingsection hingedly mounted on the other edge of the back, and means in said housing for locking the hinged clamping-section.

2. A binder comprising a back, a housing at one end thereof, a stationary clamping-section secured to one edge of the back and to said housing, a second clamping section hingedly mounted on the other edge of the back, means in said housing for locking the hinged clamping-section, and a filing-pin attached to said hinged clamping-section.

3. A binder comprising a back, a housing at each end thereof, a clamping-section movably mounted at one edge of the back, a device in each housing, having connection with said clamping-section to lock the same, and an operating-shaft extending longitudinally through the back and connected with the said devices.

4. A binder comprising a back or main portion, a clamping-section movable thereon, a rocker, a connection between the rocker and clamping-section, a spring, a dog carried by the spring and coacting with the rocker, and a movably-mounted member carried by the back for flexing the spring to retract the dog.

A binder comprising a back, a housing at each end thereof, a clamping-secti on movably mounted at one edge of the back, a device in each housing having connection with the clamping-section to lock the same, and an operating member extended longitudinally of the back and connected with both of said devices.

8. A binder comprising a back or main portion, a movable clamping-section, a rocker, a connection between the clamping-section and rocker, a dog coacting with the rocker, and a .cam adapted to move the dog into inactive position.

i 9. A binder comprising a back or main por- !tion, a movable clamping-section, a rocking 'disk, a connection between the rocking disk and the clamping-section, said disk having ishoulders on its periphery, a stop lying between the shoulders to limit the rocking move }ment of the disk, and means for releasably F locking the disk against movement.

10. A binder comprising a back or main portion, a movable clamping-section, a rock- Eing disk, a connection between the rocking disk and the clamping-section, said disk having shoulders on its periphery, a stop lying between the shoulders to limit the rocking movement of the disk, means for releasably locking the disk against movement, said means comprising a dog adapted to engage the disk, a spring carrying the dog, and means coacting with the spring to move the dog into inactive position.
